Bad: aliens that insist upon referring to human women as “feeeeemales”.
Good: aliens that insist upon dividing humans into binary categories, but the binary in question is based on something we’d regard as trivial and bizarre.
M2 9: Wings of a Butterfly Nebula : Are stars better appreciated for their art after they die? Actually, stars usually create their most artistic displays as they die. In the case of low-mass stars like our Sun and M2-9 pictured above, the stars transform themselves from normal stars to white dwarfs by casting off their outer gaseous envelopes. The expended gas frequently forms an impressive display called a planetary nebula that fades gradually over thousands of years. M2-9, a butterfly planetary nebula 2100 light-years away shown in representative colors, has wings that tell a strange but incomplete tale. In the center, two stars orbit inside a gaseous disk 10 times the orbit of Pluto. The expelled envelope of the dying star breaks out from the disk creating the bipolar appearance. Much remains unknown about the physical processes that cause planetary nebulae. via NASA

Swirling bands of light and dark clouds on Jupiter are seen in this image made by citizen scientists using data from our Juno spacecraft. Each of the alternating light and dark atmospheric bands in this image is wider than Earth, and each rages around Jupiter at hundreds of miles (km) per hour. The lighter areas are regions where gas is rising, and the darker bands are regions where gas is sinking. This image was acquired on May 19, 2017 from about 20,800 miles (33,400km) above Jupiter’s cloud tops. Learn more

space documentary: In about 5 billion years, our sun will enter its red giant phase, destroying Mercury, Venus, and possibly Earth as well.
me, knowing full well that there’s no way I will be alive by then:

hey, don't cry. comet C/2022 E3 (ZTF) visible to us humans for the first time in 50,000 years before it'll leave us forever, ok?

u know what’s my favourite from the 55 greetings to potential extraterrestrials from the Voyager. the Punjabi one. “Welcome home. It is a pleasure to receive you.” like. look, i know i’m reading too much into this, but. the implication of “welcome home”… that a universe in which we are no longer alone feels more like home. that when we find each other in the emptiness of space it’ll feel like coming home.
Over 90% of our solar system actually begins where the planets end. Deep stuff. Yes, the galaxy is interesting, but our own cosmic backyard should pique our interest as well. Lots of interesting things just a hop, skim, and few year journey in a yet-to-be-designed spacecraft.
So the James Webb telescope just took a picture of a galaxy that is 29 million light years away.
If that wasn't cool enough NASA decided to peel away all the cosmic dust in order to see the bones of the Galaxy itself.
AND IT'S BREATHTAKING
seeing the photos from Webb up against photos from Hubble just makes me… I don’t even know like, wow! Look at that!
andrei, he/him, 21, made this at 14 when i was a space nerd but i never fully grew out of that phase so,,,,..,hubble telescope + alien life + exoplanet + sci fi nerd
